Extract Pictures from PDF with C# REST API

In this fast‑track tutorial you’ll learn how to extract pictures from PDF using a C# REST API. We provide everything you need to configure the development environment, a clear step‑by‑step guide to build the converter, and instructions to retrieve images from a PDF with the C# REST interface through the .NET‑based Cloud SDK. By the end of the guide you’ll be able to pull images from a single page or from all pages of a PDF.

Steps to Extract a Picture from a PDF with C# .NET-based API

  1. Configure the PdfApi object by setting the API Key and Application SID for extracting images
  2. Upload the source PDF file with images to the Cloud storage
  3. Call the GetImages() method with the uploaded PDF file name and target page number
  4. Parse through all the images in the list and get the image ID
  5. For each image call the GetImageExtractAsJpeg() method with the name and image ID to download the image
  6. Save the image with a unique name on the disk

These steps summarize how to extract image from PDF with C# Low Code API. Create the PdfApi object, upload the source PDF file using the PdfApi, and get a list of images in the source PDF file using the GetImages() method. Iterate through the list to get the image ID and use the GetImageExtractAsJpeg() method to fetch the image and save it on the disk.

Code to Extract Figure from PDF with C# RESTful Service

This example shows how to export images from PDF with C# Low Code API. Although the sample pulls images from a single page, you can simply iterate over all pages in the PDF and retrieve either every image or a selected subset by using the image index. By combining the page number with the image index, you can assign a unique name to each downloaded image.

Now you’ve mastered extracting images from a PDF with the C# REST API. When you’re ready to embed images back into a PDF, see our step‑by‑step guide on Insert Image into PDF with C# REST API.
